actually, no offense meant, but you have no idea what so ever what you are talking about.

in the 80's a program was started in the US to stop drug traffic on the highways. one man came up with the program, and tought state stroopers how to look for drug smugglers. he was able to come up with a program that could be tought in half a day to troopers, that allowed the number of arrests for transporting drugs to skyrocket. basically, it comes down to a relativly simple formula - if every day from 10 am to 4 pm the vast majority of cars on a stretch of road are either single men in sedans wearing suits, or women in minivans driving around kids (for instance) if you see something totally out of pattern, pull them over and start asking questions. if they are calm and clear, let them go, if they are flustered or combative, look around and search the car.

the 19 members of 911, as well as most of the other terrorists that have highjacked planes in the past 20 years, as well as the "shoe bomber" from england, all exibited very strange activities on their way to the planes they borded. if anybody had been on the lookout for these patterns, they couldhave been stopped (as a matter of fact, the shoe bomber was stopped in israel when he tried to fly).
